Performance Testing and Criteria for Snowmobile Seat Cushions 730770
A reliable and practical test method has been developed to measure the dynamic cushioning properties of snowmobile seats. These cushioning properties are related to probability of spinal injury to man impacting such cushions and minimum performance levels are recommended. A review of the dynamic cushioning properties and performance of many snowmobile seat cushions demonstrates the effects of cushion construction on performance. This test method and relation of data to injury probability provides the engineer the tool with which to design safety scientifically into snowmobile seat cushions.
